Page 3: Research news on plate divergence

Plate divergence is a tectonic phenomenon in which lithospheric plates move apart along divergent plate boundaries, driven primarily by mantle convection, slab pull, and ridge push forces. This separation promotes decompression melting of the underlying asthenosphere, generating mafic magmas that ascend to form new oceanic crust at mid-ocean ridges or intraplate rift systems on continents. The process is characterized by extensional stress fields, normal faulting, and symmetric seafloor spreading, often accompanied by linear volcanic and seismic activity. Plate divergence plays a central role in lithosphere recycling, global heat loss, and the long-term evolution of ocean basins and continental configurations.

Deep heat beneath US traced to ancient rift with Greenland

A large region of unusually hot rock deep beneath the Appalachian Mountains in the United States could be linked to Greenland and North America splitting apart 80 million years ago, according to new research led by the University ...

Scientists detect deep Earth pulses beneath Africa

Research led by Earth scientists at the University of Southampton has uncovered evidence of rhythmic surges of molten mantle rock rising from deep within the Earth beneath Africa. These pulses are gradually tearing the continent ...
